Title: Tri-state buffer
Inventor: MORIMOTO TAKAHIRO
IPC: H03K19/0175
Filed: 1990-01-31
Abstract: PURPOSE:To suppress ringing at a change in an output signal by providing a through-rate control circuit receiving a gate voltage of a transistor(TR) constituting a final stage of a tri-state buffer as a proper value. CONSTITUTION:When an earth potential is given to an input terminal 18, a voltage set to an IcN terminal 13 is transmitted as a gate voltage of an n- channel MOS TR 2 and a power voltage is fed to the gate voltage of a p- channel MOS TR. Then each ON resistance of TRs 1, 2 being final stage components of the tri-state buffer is higher than usual. Since a through-rate control function is realized when a QE terminal 5 is set to the power voltage, an output suppressing ringing is obtained at a change in the output signal. Thus, the malfunction due to ringing is prevented.

Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To suppress uneven friction of a shoulder part without deteriorating drainage property and an external appearance in the last period by forming a sipe which opens to a tread end in the vicinity of an acute angle corner part which contacts ground and at the same time extending the sipe in a direction parallel with the inclined groove toward the inside of a block from an open part, while its end is kept inside the block. SOLUTION: On both end partsteelarge number of block B are arranged in a circumferential direction, and a direction in which the inclined groove extends is set to 360 deg. with respect to a circumferential direction. Furthermore, a groove depth of the inclined groove and the circumferential direction groove is set to 8mm, the length of the block which is measured to a circumferential direction is set to about 31mm. Next, when a pipe is placed in a direction parallel with respect to the inclined groove, KC and KF parts are moved so that the parts are separated from the main body of the block. A pull force from a part which is separated first can be severed. Furthermore, a compression rigidity is lowered, and a grounding pressure is reduced with the result that the friction can be reduced. As a consequence, the drainage and the external appearance at the last period is not worsened.  Furthermore, uneven friction of the shoulder part can be suppressed without lowering a controllability.

Title: Heating method and heating arrangement
Inventor: TAKE TATSUO
IPC: G03G15/20
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To enhance the heating efficiency of a heated body and to simplify the construction of a heating source by forming recessed and projecting parts on the surface of the heated body. SOLUTION: A plurality of grooves 15 is surrounded around the inner wall of a cylinder 10 to form recessed and projecting parts. When a current J flows through a coil conductor 11, the coil conductor 11 becomes a magnetic flux generating source. An eddy current I is generated in the cylinder 10 to flow in the direction opposite to the direction of the current J and bypasses in a wave shape because of flowing on the surface of the recessed and projecting parts. The resistance loss generated in the cylinder 10 when the eddy current I is flowing is proportional to the length of the path which the eddy current I flows. Thus, in order to increase the amount of the heat generation of the cylinder 10, only to do is to elongate the path length.  Therefore, the eddy current I flows in a wave shape in the cylinder 10 so that the path length that the eddy current I flows becomes longer and the heating efficiency is enhanced. Consequently, the injection energy of the magnetic flux generating source as a heating source can be saved.

Abstract: PURPOSE:To protect detecting elements without decreasing the detecting accuracy of air flow rate by coupling a protector so as to cover a part from the tip part of a holder to the drum part thereof. CONSTITUTION:The tip of a holder 3 is coupled into a side wall 23 of an air path 22. The holder 22 is provided and exposed to the inside of the air path 22. The holder 3 has a protector 4 which is coupled into the holder and covers a part from the tip end part to a drum part 3b. Air-flow-rate detecting elements 1 and 2 are surrounded with a tip 3c of the holder 3 and the inner surface of the protector 4 which faces the tip 3c, and a path space S which is a part of the air path 22 is formed. In this way, the air-flow-rate detecting elements such as the hot wire 2 which is attached to the tip end surface 3c of the holder and the temperature compensating wire 2 are protected with the protector 4. Therefore, the air-flow-rate detecting elements 1 and 2 are protected with the protector 4 when the air-flow-rate detecting elements 1 and 2 are taken out of and assembled into the air path 22.

Title: Method of depositing columnar plating in fine hole
Inventor: SAKURAI HITOSHI
IPC: H05K3/24
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To form columnar and straight bump electrodes at fine holes of a structure, by plating the inside of the fine holes with a liq. powerfully oscillated near the holes by an ultrasonic stirring at specified frequency. SOLUTION: A plating bath is not limited so long as it is not the type of corroding a substrate having fine holes and resist. An ultrasonic wave for stirring a plating liq. is set at 40kHz-1MHz and applied to uniformly diffuse the plating liq. in the fine holes and grows the plating straightly without laterally spreading even when the plating is over the height of the resist. If the frequency is less than 40kHz, the bubbles due to he cavitation are larger than the fine holes and hence cannot provide a sufficient stirring effect in the holes. If exceeding 1MHz, the stirring effect is poor.

Title: X-ray aligner
Inventor: TANAKA RYOJI
IPC: G21K1/06
Filed: 1988-02-03
Abstract: PURPOSE:To simplify an aligner and thereby to improve a throughput, by a method wherein a soft X-ray whose irradiation area is expanded by the scanning of an oscillating mirror provided in a helium chamber is taken out into the atmosphere from an X-ray takeout window, and a mask and an alignment mechanism of a wafer are provided in a region of irradiation with the ray. CONSTITUTION:A synchrotron radiation light generated in an electron accumulation ring is introduced into a helium chamber 2 through a beryllium window 3. Since the beam of the light is shaped to be 10mm wide and several millimeters high on the occasion, the shape of the beryllium window 3 may be small in area and consequently a mechanical strength increases. Therefore it is durable sufficiently even when the thickness thereof is 100mum or less, and a strong soft X-ray is taken out. The soft X-ray scanned by an oscillating mirror 4 is introduced into the atmosphere through a thin film 5 of polyimide. In order to prevent the attenuation of the soft X-ray, the thin film 5 of polyimide and a mask 7 are disposed as close to each other as possible, and a pattern on the mask 7 is transferred onto a wafer 7. Since the mask 7, the wafer 8 and an alignment mechanism 6 are set in the atmosphere in this way, operability is improved and the mechanism itself is simplified.
